Background:

• Pigeonpea [Cajanus cajan (L.) Millsp.], or redgram, is a vital grain legume in the semiarid tropics, crucial for food and fodder in India and globally.
• Enhancing pigeonpea productivity faces challenges from pests and limitations in conventional breeding due to genetic variation.
• Genetic engineering offers a powerful tool to introduce desirable traits and overcome breeding barriers in pigeonpea.

Purpose of the Study:

• To describe an efficient and reproducible Agrobacterium-mediated transformation protocol for pigeonpea.
• To facilitate genetic manipulation for improved agronomic traits in diverse pigeonpea genotypes.
• To advance pigeonpea improvement through modern plant transformation techniques.

Main Methods:

• Development of an Agrobacterium-mediated transformation protocol.
• Focus on efficient plant regeneration as a prerequisite for genetic transformation.
• Application of the protocol across diverse pigeonpea genotypes.

Main Results:

• A simple, efficient, and reproducible Agrobacterium-mediated transformation protocol for pigeonpea has been established.
• The protocol is applicable to a wide range of pigeonpea genotypes, enhancing its utility.
• This method overcomes limitations of conventional breeding for pigeonpea improvement.

Conclusions:

• Agrobacterium-mediated transformation is a key technology for advancing pigeonpea genetic improvement.
• The developed protocol provides a reliable method for introducing agronomically useful traits.
• This breakthrough supports precision breeding and enhanced productivity in pigeonpea.
